BALING PRESS i Filed Deo. 12, 1951 3 Sheets-Sheet 3 #ff/wf BY 4 WZ ATTORNEY Patented Oct. 24, 1933 i UNITED STATES PATENT OFFICE BALIN G PRESS Application December iz, 1931 serial No. scossa Claims.

nThis invention pertains to baling presses,l and more particularly to a triple Vcompression press. The invention has primarily for its object to provide a comparatively simple, economical and 5 efficient press of the foregoing' type, having an exceptionally large baling chamber for bulky scrap, and which can be operated in a manner similar to a conventional double compression press for baling small, compact scrap or clippings.

object resides in the provision of a triple compression press, in which the final high compres:

sion is eifected\between solid walls.

Another object resides in the provision ,of a press of the foregoing type, including an elongated press box, in which the initial compression is performed transversely, the second compression longitudinally, andthe third compression vertically.

A stm further and highly important object resides in the provision of a press box having a restricted offset pocket, in which the nal high compression is effected. l

With the above and other objects in view, which will appear as the description proceeds, the` invention resides in the novel construction, combination and arrangement of parts substantially as hereinafterldescribed and more particularly defined by the appended claims, it. being understood that such changes in the precise embodiment of the herein disclosed invention may be made as come within the scope of the claims.

In the accompanying drawings is illustrated one complete examplek of the physical embodiment of the present invention constructed according lto the best ,mode so far devised for the practical application of the principles thereof.

In the drawings:

Figure 1 is a longitudinal section through a press constructed inaccordance with the present. invention.

Figure 2 is a plan view with parts broken away and in section.

3--3 of Figure 1.

Figure 4 is a fragmentary plan section, illusi tratlng the manner in which the initial compression is obtained.

` Figure 5 is a similar view illustrating the second compression, and

Figure 6 is a fragmentary section illustrating the final compression.

In carrying out the present invention, various conventional features are employed, such as a sliding cover andthe usual compression rams. Therefore, the same form no specific part of the present invention, which is directed broadly to the manner ln which the respective compressions are effected, andthe highly novel design of the press box. o

Incidental to the foregoing, a more specific Figure 3 is a vertical section taken on the linoD (ci. 'i4-42) In the drawings, the numeral 1 designates the press box, which is preferably positioned within the well 2, and supported upon the transverse beams 3 withl the filling opening substantially `level with the hoor line, thus facilitating filling of the box. Slldably mounted above the box is the usual cover 4, which is` supported by the wheels 5 mounted upon the stub shafts carried by the blocks 6, which in turn are resiliently connected with the brackets 7 to the studs 8 and the-coil springs 9. Normally a slight clearance is provided between the cover 4 and the top of the press box, to permit easy actuation of the same, by means of the piston 10 and the fluid cylinder 11.

When the cover 'is reciprocated to closed position, the same is urged into intimatecontact with the top of the press box in the usual manner, which, in the present instance, comprises lateral rollers-12 carried by the rear of the cover and engaged under the cam plates 13 carried by brackets 14 secured to the top of the press box. The front of the cover is forced downwardly into engagement with the top of the press box by means of a head yoke 15 mounted upon theltop of the press-box and provided with a cam plate 16 which engages the wedge boss 1-'7 provided on the front end of the cover.

As best shown in Figure 2, the press box 1 is also open at one side and is provided at its forward end with an offset 'pocket 18 positioned at one side of the box and'extending longitudinally therefrom.

sudably mounted within the box ,is a conventional ram 19, which forms one side of the box.

and is actuated transversely therein by a pair of fluid pressure cylinders 20 to effect initial compression of material contained within the box.

As best shown in Figure 2, the cylinders 20 are carried by a longitudinal beam 21 secured to the arms 22 projecting, laterally from the press box.

Counterweights 23, connected with the ram 19 by means o f cable trained over the pulleys 24, serve `to return the ram to normal position when the ,fluid pressure is released within the cylinders 20. iThe secondary compression is obtained by the ram 25 actuated longitudinally of the press box l by means of the pressure cylinder 26. The ram 25 is also provided with a counterweight 27 for returning the same to normal position.

The third, or final, compression, which is effected within the odset pocket 18, is obtained by the vertical ram 28 operating through the bottom of the press, and actuated by the pressure cylinder 29, carried by the ncrosshead v:30, which is supported below the press box by the tie rods 31, which also serve to secure the head yoke" 15 to the press box. Th e ram 28 is returned to normal position through gravity, no counterweight being required. i

From the foregoing explanation, taken in connection with the accompanying drawings, it is believed that the operation of the present invention will be readily apparent, in that when it is desired to bale bulky scrap, such as automobile fenders, body parts, discarded steel furniture, drums, barrels, and large, fiuffy clippings, into a neat, compact bundle of minimum dimensions, the scrap is placed within the press box 1, after which the cover 4 is shifted to closed position, and securely engaged with the top of the press box, as heretofore explained. The ram 19 is then actuated to obtain initial compression transversely of the press box, and throughout its entire length, as best illustrated in Figure 4. The longitudinal ram is then actuated to obtain the second compression of the scrap within the offset pocket 18. Lastly, high compression is ob-l tained by means of the vertically actuated ram 28, which Works against the forward end of the cover 4 that projects over the pocket 18, and which is locked in position by the rigid head yoke 15.

Thus it will be seen that an exceedingly simple, economical and eflicient triple compression press has been provided, in which the three compressions are obtained by three sets of hydraulically actuated rams. The iirst compression isffrom the side, the second compression in a longitudinal direction, and the third and final compression from below by means of the vertical ram, which also serves to eject the bale from the pocket 18 when the cover 4 is withdrawn. The final compression, being made between solid walls at the high pressure end of the press box, assures a neat andv compact bale free from fins and loose pieces. y

Further, inasmuch as'the initial compression is from the side, an extra large baling chamber for bulky scrap is permissible, and which, in spite of its size, permits speedy and eflicient operation. and an exceedingly simple, sturdy and `rugged construction. Few moving parts are employed, making the maintenance readily comparable with that of an ordinary double, compression type of baling press.

The manner in which the respective compressions is obtained also offers, in addition to affording an exceptionally large chamber for bulky scrap, the equivalent of a conventional double compression press for baling small, compact clippings,l by simply leaving the first compression head or ram 19 in advance position, as illustrated in Figure 4, and utilizing the second and third,

compressions only, thus meeting all conditions and providing ideal equipment for Lscrapyard service.

The press is constructed entirely of lheavily ribbed steel castings securely bolted together, insuring permanent alinement and prevention of distortion. As is customary, the press'box is alsolined with easily renewable steel plaies.

.Particularattention is directed to further ad- .vantages resulting from the novel vconstruction of a press box -provided with an offset pocket, in that final compression is obained between three solid walls, a feature heretofore only obtainable in conventional double compression presses. Also, the foregoing arrangement permits thetop yoke and vertical cylinder assembly to be constructedproportionately to the of the box, thus providing a compact and ex- .tremely rigid structure.

'complished by a comparatively short stroke, a

minimum period of time is required for the operation.
